The ferroelectric phase of the parent BaAl2O4 is largely suppressed by the Sr-substitution and disappears for $x\\geq0.1$. Structural refinements reveal that the isotropic atomic displacement parameter ($B_{\\rm iso}$) in the bridging oxygen atom for $x\\geq0.05$ is largely independent of temperature and retains an anomalously large value in the adjacent paraelectric phase even at the lowest temperature.
